IP Address The options available in this field vary by DDNS provider.
Interface -The Zyxel Device uses the IP address of the specified interface. This option
appears when you select a specific interface in the Primary Binding Address Interface
field.
Auto - If the interface has a dynamic IP address, the DDNS server checks the source IP
address of the packets from the Zyxel Device for the IP address to use for the domain
name. You may want to use this if there are one or more NAT routers between the Zyxel
Device and the DDNS server.
Note: The Zyxel Device may not determine the proper IP address if there is an
Custom IP - If you have a static IP address, you can select this to use it for the domain
name. The Zyxel Device still sends the static IP address to the DDNS server.
Custom IP This field is only available when the IP Address is Custom. Type the IP address to use for the
domain name.
Backup Address Use these fields to set an alternate interface to map the domain name to when the
interface specified by the Primary Interface settings is not available.
